Ugg boots, please advise!

[Flight]

I am looking at some second hand, they are tall with a big fur turnover at the top. The label on the back is goldy coloured, not sure if it says UGG as the photo is a bit blurry.
But they are lovely. Seller asking £120. I am willing to invest if they are the genuine article but can anyone tell me if this is too much or if they might be fake?

They don't look at all like the suede short ones which I hate, btw!

TIA

Thanks worley. I might look at that for next year if I don't get some Celtic's, but will deffo look at getting some reefs for dh and some Fannings for me (the flip flops with a bottle opener in the bottom - v handy!) from the States.
